Close working distance
At the high reproduction ratios used in close-up shooting,
the depth of field is very shallow. To ensure greater depth of
field, stop down the lens, then carefully position the camera
to ensure the most important surface of the subject is in the
same zone of sharp focus.
• Use manual focus when using the close-up lens.

8. Exposure factor
The f-number of a lens indicates brightness of the image
formed by the lens set at "infinity" shooting distance. The
higher the reproduction ratio is, the more the brightness
of the image will decrease. The actual brightness of the
image is called the "effective f-number," and the exposure
compensation value for the change of the effective
f-number is called the "exposure factor."
9. Effective f-number variation (P. 152)
With this lens, the higher the reproduction ratio is, the
more the brightness of the image on the film (image
sensing device) will decrease and the effective f-number
will increase (the amount of light that comes through the
lens´ aperture will decrease). This variation is automatically
compensated for by the camera´s exposure meter, so the
user can determine exposure or operate TTL flash shooting
without having to consider the exposure factor.
The f-number displayed in the camera´s LCD panel or
viewfinder is the value automatically compensated.
